Odisei Play · In production

Saxophone or clarinet. The app responds.

Odisei Play supports Travel Sax, Travel Clarinet, acoustic saxophones and acoustic clarinets, with real-time feedback as you play. The audio engine, pitch detection and game screen are the work of Kim Chouard, the CTO. We were two developers and a designer, shipping a release every two weeks.

38% of the repo’s 14,778 commits are mine. Counted September 2026.

Offer 01 · Web and mobile apps

From Bluetooth to the app stores.

Architecture, code review, animations and builds. I take responsibility for your React Native app and work with your designer. On your team, fully remote. Full-time or part-time, depending on what you need.

Offer 02 · AI methods

A repo your agents can read.

I prepare your codebase for working with AI agents, starting from a workflow proven over more than two years in production. Every week, a report crosses PostHog and your database so you decide what's next. Your team stays in control of the decisions and the code you ship.

Field notes

The work continues in the notes.

Bluetooth in production, Claude Code, repo rules. I write about what I build, the mistakes along the way and the fixes that hold.

About

I came to code from audiovisual.

Before code, I was an audiovisual technician. That is where I learned to hold a story together, in images and sound. Then I retrained as a developer. I have been freelance for five years now, by choice.

I'd rather be the calm one than the clever one. A messy repo is something to read before it is something to fix.

I don't think the job is to be the best coder anymore. The job is to hold an idea clearly enough that the machine can build it. And to keep the repo clean enough that it doesn't wreck it. AI extends that thinking. It doesn't replace it.

I want the work to reach someone. On Odisei Play, a person learning the saxophone. With sneq-engine, my open-source library, a player in a game that remembers its own story.
